Abstract
The brush device of a starter with an overheat protection device of the present invention is provided with brush holders, brushes slidably supported in the brush holders, respectively, springs contacting one sides of the brushes to press the brushes in the radial, inner directions, and thermostats disposed on the brushes and adapted to interrupt energization of a starting motor with a power when the brushes exceed a predetermined temperature, caused by the starting motor continuously energized with the power supply.
Claims11
A starter with an overheat protection device including a brush device provided with
- brush holders,
- brushes slidably supported in said brush holders, respectively,
- springs contacting one faces of said brushes to press said brushes in the radial, inner directions,
- thermostats attached directly or indirectly to said brushes and adapted to interrupt energization of a starting motor caused by a power supply when said brushes exceed a predetermined temperature, caused by said starting motor continuously energized with said power supply, and wherein each of said thermostats is provided in a hole of a molding with a heat resistance attached to a base fixed to a bracket of said starting motor, so as to contact said brush.
